Nuthatch Welfare in Deciduous Woodland

Nuthatches are charismatic woodland birds that plaster nest hole entrances with mud and cache food in bark crevices, holding year-round territories in mature deciduous woodland.

Key Facts

Nuthatches are the only UK bird that can descend tree trunks head-first
They plaster nest holes with mud to reduce the entrance to their preferred size
Food caching allows nuthatches to buffer against short-term food shortages
The UK population is expanding northward, possibly linked to climate change

Welfare Considerations

Nuthatch welfare is closely tied to the availability of mature deciduous woodland with large trees offering nut crops and cavity-rich bark. Loss of veteran trees reduces both nesting and foraging habitat. Competition with great spotted woodpeckers for nest holes can displace pairs from optimal territories.

What You Can Do

Retain large veteran oaks and other nut-bearing trees in woodland management
Avoid tidying bark and crevices in mature trees that provide foraging habitat
Record nuthatch territories for BTO Breeding Bird Survey
Support woodland management that retains structural diversity across age classes
